East Sussex’s geology transitions between South Downs chalk and Wealden clay – both presenting distinct foundation challenges. Chalk bearing capacity varies unpredictably, with voids and soft zones appearing without surface indication. Wealden clay exhibits significant seasonal movement as moisture content changes. Our helical pile foundations adapt through installation – real-time load testing confirms capacity, and pile depth extends immediately when weak ground appears.

The county sits largely within the South Downs National Park and High Weald Area of Outstanding Natural Beauty, where planning applications face environmental scrutiny. Our screw pile contractors deliver minimal excavation, no concrete mixing on-site, and reversible methodology that satisfies planning requirements for sensitive landscapes.
